Greenhouse Gas Assessment


Greenhouse gas (GHG) assessments offer a valuable way to compare the effectiveness of multiple energy and sustainability best practice actions over time.  GHG assessments support planning for sustainability by defining a baseline, tracking a trajectory, and measuring outcomes of sustainable strategies.  They can also track progress toward meeting the State’s goals regarding energy efficiency and greenhouse gas reduction, and can be used for cities to set their own targets and track progress towards energy or climate goals. 

Maplewood GHG Assessment

In 2016 Ted Redmond, co-founder of Pale Blue Dot, LLC (, and a resident of Maplewood, donated his services to the City to complete a GHG baseline assessment.  Here is a summary:

City-Wide GHG Assessment:

  The city-wide data was established for the year 2013 through the Regional Indicators Initiative ( and include energy use, travel and transportation, water use, solid waste, and wastewater.  It does not include indirect emissions associated with food and product purchases, or with services provided residents and businesses outside of City boundaries.  City-wide 2013 GHG emissions totaled 487,020 Metric Tonnes of CO2 equivalent (impact of all greenhouse gases), 55% of which is produced by residential and commercial energy use.  This represents a per capita emission of 12.12 Metric Tonnes.

City-Operation GHG Assessment:

  The city-operation baseline data was collected for the year 2015 and calculated for the first time.  City operation emissions include city buildings and grounds, streetlights and signals, city vehicles, employee travel and transportation, water and wastewater, and solid waste.  City-operation 2015 GHG emissions totaled 5,267.41 Metric Tonnes, which is 1.08% of city-wide GHG emissions.  It represents an emission rate of 31.92 Metric Tonnes per employee, 48.37 pounds of CO2 equivalent per city facility per year.
